RIVETING MACHINE.

Application filed October 26, 1921. Serial No. 510,518.

To all whom it may concern:

Be it known that I, JOSEPH O. BAILEY, a citizen of the United States, residin at Atlanta, in the county of Fulton and btate of Georgia, have invented new and useful Improvements in Riveting Machines, of which the following is a specification.

This invention relates to riveting apparatus, more particularly it is directedrto an improved automatic riveter, universally adjustable to meet riveting requirements in the construction of spiral conveyers.

()ne of the principal objects of this invention is to design a fluid operated jawtype riveter for effecting the riveting operations in the construction of either continuous or sectional flight spiral conveyers, the

' capable of effectively operating in the narrow confines of the flight pitch and with the riveting jaws properly disposed to correctly align the rivet'when' driven through the conveyer flight.

Other important objects of this invention are to materially expedite the construction of spiral conveyers by reducing the time and labor incidental to the rivetal union of their components, to provide a machine with rivet set easily and quickly adjustable to the flight angle of either right or left hand conveyers, and, to produce a riveting machine of an extremely flexible character which will, concomitantly with the riveting operation, function to draw the conveyer flights taut about the conveyer.

With these and other objects in view, which will become apparent as the description proceeds, the invention resides in the construction, combination, and arrangement of parts, hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which like characters of reference indicate like parts throughout the several figures, of which:

Figure l is a perspective view of the riveting machine forming the subject matter of this invention;

Figure 3 is a fragmentary 's'e'ctionized detail of the riveting and Figure t is a fragmentary sectionize'd dctail, partly in elevation, illustrating the rivet-set 1n compressed position and securing the inner extremity of a In used for anchoring the conveyor flight to t e shaft.

Briefly stated, this invention comprises a pair of complemental jaws pivoted upon a shaft in opposed relation and having their operating ends formed with suitable rivetsets and their power ends connected to a fluid controlled operating mechanism, the

jaws and their mounting;

pivotal shaft of the complemental jaws being carried by an annular casting rotatabl'y supported in a ring swi-vellymovable about its vertical axis. i

In the construction of either continuous or sectional flight conveyers, the rivetal union of their components has always been a tedious and laborious operation owing to the continually changing angle of the con? Veyer flights, which rendered positionme'nt of the rivet in true rivet alignment with the conveyer extremely diflicult, and not infrequently resulted in offset riveting. It is, therefore, the aim and'p'urpose of this invention to provide a simple mounting for the riveting jaws which will materially expedite this work, and enable the rivetsj to be accurately aligned and compressed with a minimum loss of time. r

In the illustrated embodiment 'characteria ing this invention, there is shown a pair of elongated complemental jaws 7 formed with pivotal lugs 2, aperturedfor the passage of a shaft 3. The operating ends of j aws'l are provided with rivet-sets 4E and 5, while their power extremities arevconn'ected bycmean's of toggle links 6, to a fluid-operateddriving mechanism 7, controlled by a foot-lever 8. This structure is of substantially stand ard design and has been referred to solely for the purpose of aiding the disclosure of the present invention. 7

In order to obtain the desired adjustment of riveting jaws 1, the extremities of shaft 3 are fitted into oppositely positioned sockets 9 formed on. the inner circumferenceof an internal ring 10. This ring 10 is formed with a circumferential tenon ll adaptedto seat in channel 12 formed in the innercirv I v cumference of external ring 13,. Figure 2 1s a fragmentaryfront elevation;

Ring 13 is cast in upper and lower semicircular sections, the extremities of which I are formed with lateral ears 14, suitably ting of the external ring at any predetermined angle. To secure the external ring at the desired angle, socket 17 of swivel plate 18 is provided with a set-screw 20.

With the parts assembled as described, it is evident the mounting provided affords in effect universal adjustment of the rivet-set.

In the construction of spiral conveyers, with a machine designed in accordance with the preceding, a conveyer shaft equipped with a suitable number of sectional flights is horizontally suspended within operating distance of the rivet-sets 4 and 5. Jaws 1 of the machine are then adjusted until the rivet-sets are positioned in proper rivetal alignment with the overlapping extremities of the flight sections whereupon the rivets are inserted and compressed. Obviously with the riveting jaws adjustable in this manner, true driving alignment of the rivet may be quickly and accurately obtained for any angle of conveyer flight of both right and left hand conveyers. After the riveting jaws have been rivetally positioned they are locked and remain in this position until the desired quantity of conveyers has been produced.

In addition to rivetally uniting the extremities of the sectional conveyer flights, this machine serves to draw the flights taut about the conveyer shaft, and likewise enables the several lugs securing the flights to the shaft, to be readily headed by hand; that is to say, the operator is enabled to place a rivet through the opening in lug and flight, compress the rivet, and then hold rivet-sets in compressing position thus securing the lug against movement while hand riveting its outer end, as shown in Figure 4. Heretofore it has been practically impossible to efiect this operation owing to the difliculty experienced in properly securing the lug while heading its outer end to the conveyer shaft.

In conclusion it is seen that the foregoing structure produces a simple riveting machine for the construction of spiral conveyers which can easily and quickly be adjusted to any angle that riveting of the flights of the conveyer may require.

Although in the foregoing certain elements have been referred to as being best adapted to perform the functions allotted to them, it is to be understood that various minor changes as to the arrangement of these elements, their form, etc., may be resorted to without departing from or sacrificing any of the principles of this invention.

Having thus described my invention, and without enumerating variations and equivalents, what I desire protected by Letters Patent is as set forth in the following claims.

1. A riveting machine comprising in combination, complemental power actuated riveting elements, and supporting means adjustable about vertical and horizontal axes for efiecting universal adjustment of the said elements.

2. A riveting machine comprising in combination, complemental power actuated riveting jaws, and a supporting structure of separately adjustable sections having movement about a vertical and a horizontal axis, respectively, for jointly effecting universal movement of the said jaws.

3.
